Enterprise Architecture Frameworks & the Holistic Perspective Trends Holistic Architecture: By 2006, 20% of Global 2000 organizations will integrate holistic enterprise architecture, enterprise program management, enterprise strategy/planning, and IT portfolio management into a common set of IT management processes under the auspices of the CIO’s office. Ten percent will operate these integrated management disciplines outside the IT organization. Value of Integrated Architecture: By 2007, 50% of Global 2000 enterprises will move beyond a pure technology architecture focus to include enterprise business architecture, enterprise information architecture, and enterprise solution architecture. Architecture teams that fail to move beyond the technical focus will come under increasing pressure to demonstrate business value. Source: META GROUP RESEARCH ~ EA TRENDS 2004 – 2005. So, EA Frameworks has to support the holistic perspective……… and more..
